ArcGIS GeoAnalytics Server tasks that have the out
property in their context
parameter will save results in the
specified spatial reference. If you are saving the results to the spatiotemporal data store all results will be
projected to World Geographic Coordinate System 1984 after analysis for storage and the out
will not be used.
It is more common to set the processing spatial reference than the otput spatial reference. Set the spatial reference
that results will be analyzed in using the Process Spatial Reference.
Output spatial reference syntax:
"outSR": {"wkid": <wkid>}
wkid
is the well-known integer ID of a spatial reference. See Using spatial references
for the list of supported spatial references and their IDs.
Spatial Reference example (GCS_WGS_1984)
"outSR": {"wkid": 4326}
You may use a different spatial reference for analysis (process
), output spatial reference (out
) and for
defining the processing extent
(See: Extent).
For example, you can define the extent
usig wkid
4326 (GDC_WGS_1984) and save the results with wkid
3857 (WGS_1984 Web Mercator - auxiliary sphere):
Extent, dataStore, and outSR example:
"context" : {
"extent": {
"xmin": -122.68,
"ymin": 45.53,
"xmax": -122.45,
"ymax": 45.6,
"spatialReference": {
"wkid": 4326
}
},
"outSR": {"wkid" : 3857},
"dataStore": "relational"
